In my previous posts, I had explained the trials and tribulations of upgrading my 5 year old Dell Inspiron 1501 laptop. Knowing that the “not charging” problem was either the battery or the AC adapter, I ordered a replacement AC adapter from a reputable seller on Ebay. After plugging the new AC adapter in, I still had the same problem.
A week or so later, I was trying to repair a customers’ Dell of the same model that was DOA, and I took their battery out and placed it in mine. Voila, it started charging, both with the old AC adapter and with the new one. After returning the customers’ battery to their unit, I starting looking for a new battery on Ebay. Looks like I can get a new OEM battery for around $35.
